FEEDING DEVICE FOR PENCIL S.

Specification of Letters Patent. 3 Patented A g 13 1918 Application filed January 3, 1918. Serial No. 210,202.

To all whom it may concern:

Be it known that 1, WILLIAM P. MANUEL, a subject of the King of Roumania, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Feeding Devices for Pencils, of which the following is a specification.

This invention relates to means for feeding leads, erasers'and the like, and pertains especially to lead pencils.

It is an object of this invention to provide a feeding device, by which a material to be used, such as an eraser ora lead, may be projected or retracted at will. Thus, in the case of a lead, it may be projected when it is desired to..use it, and retracted when not in use. It also serves tofeed more of the lead as the latter is worn away. Inthe case ofan eraser, it may form part of an attachment to be applied to a pencil, and the eraser may be projected to compensate for wear.

I accomplish these objects by means of the embodiments of my invention illustrated in the accompanying drawings, in which;

Figure 1, is a perspective view of a pencil I having an attachment secured thereto embodylng a preferred form of my lnvention.

Fig. 2 is an enlarged sectional view of the attachment shown in Fig. 1. Figs. 3 to 6 inclusive are elements of the attachment disassembled. Fig. 7 is a section as seen on a line 77 of Fig. 4 with-the display sheets removed. Figs. 8 to 11 inclusive are ele ments of a modified form of my attachment shown assembled in Fig. 12. Fig. 13 is an elevation of a pencil having my invention embodied in the -means for feeding the eraser and in the means for feeding the lead. Fig. 14 is a longitudinal section through the pencil shown in Fig. 13.- Fig. 15 is an enlarged section as seen on the line 15-15 of Fig. 14. Fig. 16 is an enlarged fragment of Fig. 14. Fig. 17 is a section asseen on the line 1717 of Fig. 14. Fig. 18 is an elevation of the eraser carrier. Fig. 19 is a section as seen on the line 19 -194 of Fig. 14. Fig. 20 is an. elevation of an attachment such as is shown in Figs. 13to 18. inclusive, but having. a sleeve adapted to. slip over and grip a pencil by friction.

Referring particularly to Figs. 1 to 7mclusive, which show thepreferred form of my invention, I have shown an attachment embodying myinvention secured to a pencil .the end of pencil P.

--P. The pencil 'P may be of the type shown in Figs. 13 and 14. However, any other suitable type of pencil may be used. The pencil shown is, however, of the type in which independent leads are fed from a casing.

The attachment is comprised of a connector A, a display barrel or holder B-, 'a shell C, an eraser carrier D-, and a cap E-. The connector -A- is of hell shape having an internal thread at its small end adapted to engage with a similar thread on A partition wall 21 divides the bell mouth from the portion [which connects to the pencil. The large end of the bell is internally threaded.

The barrel B is of tubular form and has an upper flange 22 and a lower flange 23. Longitudinal flanges 24 and 25 connect end flanges 22 and 23 and form a groove 26.

Diametrically oppositeto groove 26 is a-rib 27, which is rabbeted at the sides, forming with the flanges recesses on the face of the barrel for receiving display sheets. A neck 28 is formed'on the barrel. On neck 28 is a in 29. Formed in the bore of the barrel is a slot 30 adapted to receive a projection on the eraser holder.

The shell -C comprises a lower ring 31 externally threaded. Posts 32 and 33 connect ring 31 with an upper ring 34, the latterbeing of angular section as shown in Fig.2. On the inner surface of post 32 and ring 31 is a rib 35 adapted. to be disposed in slot 26 of the display barrel. Rotatably -secured'on ring 34 is an apron 36, which is -fixed to a feeder sleeve 37 and preferably der for abutting the feeder sleeve and tolimit its movement. Upon the ring 40 is a tongue 41 adapted to ride in the slot 30. Erasers 42 and 43 are disposed in the bore of the carrier. Eraser 42 is for use, while eraser 43 is a reverse eraser.

c and an eraser carrier 0Z.

fits loosely within the bore of the barrel and may be rotated by turning the apron 36. The eraser carrier D is then slipped into the barrel B- with the tongue 41 disposed in slot 30. This prevents rotation of the carrier, but permits longitudinal movement with respect to the barrel and sleeve. Sleeve 37 is then rotated so that the thread on the interior engages the thread 39- on the carrier. Cap E- which has a bayonet slot 4-4 is slipped upon the neck 28 of the barrel with the pin 29 in slot 44 and locked in position. The shell is now screwed to connector A- as shown in Fig. 2. The entire attachment may then be screwed on to the end of the pencil P.

It is obvious that the eraser 42 may be projected or retracted at will. eraser is worn down so that it is no longer serviceable, the attachment may be disassembled and the reserve eraser 43 placed in the position of eraser 42.

In Figs. 8 to 12 inclusive a modified form' of the device adapted to fit on the end of a pencil and provided with an adjustable eraser, is'shown. The assembled device disposed on the end of a pencil is shown in Fig. 12.

The device comprises a pencil gripping sleeve a, a display barrel b, a shell The elements a-, 7), and c are similar to the elements -A, B, and -C of the preferred form of device. The sleeve -a is slit to provide spring fingers and has a retaining member 45 fixed thereto. At its upper portion the sleeve is expanded as indicated by 46 and provided with an internal thread at the expanded portion.

The barrel b is provided with recessed faces for the reception of display sheets, as described for the holder of the preferred form, and is also provided with a groove 47 On its inner face, it is provided with a longitudinal groove 48.

The shell c-- has a lower ring 49 externally threaded and'posts 50 and 51 connecting with an upper ring 52. The upper ring 52 is reduced in diameter and rotatably mounted thereon is the apron portion 53 of a feeder sleeve 54. Sleeve 54 is of such diam- I,

eter that it will looselyfit within the bore of .barrel b and has an internal thread.

in form and'is provided with, a thread 55 upon its exterior, The lower part of the lVhen the carrier is expanded to for-man abutting shoulder 56, and extending from said shoulder is a tongue 57 adapted to engage the slot 48. Erasers 58 and 59 may be slipped into the tubular bore. I

The device is assembled in the following manner: The display barrel ?2 is telescoped within the shell c, the tongue 60 and slot 47 coiiperating to hold the holder and sleeve in proper position, the feeder 54 being within the bore of the barrel b.

The eraser carrieris now placed within the display barrel, the tongue 57 riding in groove 48, thereby preventing rotation of the carrier with respect to the display barrel, but permitting longitudinal movement .Of' the carrier. The feeder 54 is now rotated by grasping the apron 53 and turning the same, thereby engaging the thread on the interior of sleeve 54 with the thread 55 on the eraser carrier. It is evident that the eraser 58 may be projected or retracted by rotating the feeder. The assembled shell, display barrel,

It will be noticed that the eraser carrier a has an additional eraser 59. This is merely a reserve eraser which maybe substituted forthe eraser 58 when the latter is worn.

I Referring particularly to Figs. 13 to 20 inclusive, a pencil for feeding leads and an eraser feeding attachment without display means is shown. The eraser feeding mechaan internal thread 64. Secured to shell 61 at the lower portion thereof is a sleeve 65,

which has slots formed longitudinally at diametrically opposite points providing two sections. A complete ring 66 is formed at the upper part of the sleeve and is flanged to overhang head 63, thereby holding the rotatable sleeve in place. The eraser carrier is of tubular form as shown in Fig. 18 and I has upon diametrically opposite portions of its surface, sections of mutilated'thread 68 and 69. The mutilated sections of thread fit within the slots formed in sleeve 65, thereby permitting longitudinal movement of the holder but preventing rotation. Erasers 7 O and 71 are placed in the bore of the holder 67, eraser 70 being for use and 71 as a reserve eraser. The thread sections 68 and 69 mesh with the thread 64 on sleeve 62, so that upon rotating sleeve 62, the carrier 67 isprojected or retracted. Sleeve 65 is internally threaded at its lower end and adapted to engage with external threads on connector 7 2. Connector 7 2 is internally threaded and forms a cap .for the end of the pencil.

It is obvious that the eraser may be fed by turning the ring 63. When eraser is no longer useful because of-wear, the eraser 71 is substituted therefor. This change may beaccomplished' in the following manner The connector 72 is detached from the attachment and the eraser carrier removed from the shell. This may be done by turning the ring 63 in the direction toretract the carrier. 4

The construct-ion shown in Fig. 20 dif fers from that last described only in the connector 63 which takes the place of connector 72. Connector 73 is suitable for slipping onto the end ofan ordinary wooden lead pencil and is provided with a retainer 74.

Referring particularly to Figs. 13, 14 and 17 the casing for the pencil is indicated by 7 5.and is preferably of metal. A tapered end 76 is attached thereto by means of a thread on its interior, which engages with a thread on the exterior of the lower end of the casing. A rotatable tip 77 is secured to the end 76, and is'provided with a bore in which a lead. is adapted to snugly fit. Secured to the tip 77' is a sleeve 78, which is provided at its upper end with an internal thread. A shoulder 79 is formed on the sleeve 7 8 to secure the latter to the end 76.

Acarrier 80 for the lead has a thread 81 adj acent its lower end adapted to engage with the thread on the interior of sleeve 78.

. Formed on the end of carrier 80 is a ball 82.

therefrom and forming storage pockets, 50

each one of which will hold one lead. A pocket 88' to slidably receive the fin 85 is formed in the magazine. The disposition of the wing 85 in the pocket 88.prevents rotation of the carrier 80, but permits longitudinal movement. Each of the pockets for lead maybe filled with a lead, the cap formed by the connector 7 2 holding the same in place. This is a very convenient arrangement, as new leads are available for use, and it may be seen at a glance how many leads are left in the magazine.

The lead for use may be advanced or retracted by turning the tip 77 of the pencil. The thread on sleeve .7 8 engaging the thread 81 on the carrier compels longitudinal movement on the carrier and with it the lead, the Wing 85 and pocket 88 preventing rotation. The connector or cap 2 serves to limit the movement of carrierSO as the lead is retracted in the casing.
